Painless Fractions (Barron's Painless Series) - Tapa blanda

Just about everybody knows that fractions are parts of a whole number--but how many of us remember the difference between a numerator and a denominator? Or know quite what to do with them? Painless Fractions was written especially for middle-school students, but can be helpful to just about everybody. (Let's face it: we all make occasional mistakes with fractions.) The author takes a light-hearted approach to teaching fractions. She defines all terms, then demonstrates the correct methods of addition, subtraction, multiplication, and division of fractions, and shows how to convert them into decimals. Puns, puzzles, and "brain ticklers" add an element of fun to the process of mastering fractions. There are answers to all questions, and plenty of good advice for avoiding pitfalls when calculating with fractions.
